⚠️ CMHP vs. CMCP — Critical Difference:

The CMHP (this model) has a side discharge wet end with the discharge port positioned at the 12 o’clock position and the suction port centered. The CMCP (model 02593000-2010) has a center discharge wet end with both suction and discharge ports centered. Both share the same motor and frame, but the wet end orientation differs significantly. Installing the wrong model will require plumbing modifications. Verify your existing pump’s discharge position before ordering.

Measuring Your Existing Pump Connections:

To confirm 1-1/2″ connections, measure the outside diameter of the inlet and outlet fittings on your existing pump. A measurement of approximately 2-3/8″ indicates a 1-1/2″ connection. A measurement of approximately 3″ indicates a 2″ connection. A measurement of approximately 3-5/8″ indicates a 2-1/2″ connection.

115V vs. 230V — Which Do I Need?

This is the 115V model. If your spa control system provides a 230V output for the circulation pump, you need the 230V version (model 02093001-2010) instead. Check the label on your existing pump or your spa’s wiring diagram. Using the wrong voltage will damage the motor.

Replacement Compatibility:

This pump is a direct replacement for spa systems that use a 48-frame, 1-1/2″ side discharge circulation pump running at 115V/60Hz. It is compatible with Gecko spa control systems and many other brand controllers including those that provide a dedicated 115V circulation pump output. Multiple retailers confirm this pump can replace the Sundance 6500-907, Coleman ECO24-7, and various OEM circulation pumps with matching specifications.

🔧 Maintenance Guide

Routine Maintenance:

Task	Frequency	Notes
Check for leaks around seal and unions	Monthly	Look for drips or moisture at connections — pay attention to the side discharge union
Inspect union fittings	Monthly	Hand tighten if loose — do not over-tighten
Verify motor vents are clear	Quarterly	Remove debris, leaves, or obstructions from motor openings
Check mounting bolts and base	Quarterly	Tighten if vibration has loosened
Inspect amperage draw	Annually	Should read approximately 1.3A at 115V
Clean strainer/filter basket	As needed	Remove debris to maintain flow

Warning Signs — Replace or Service Pump If:

Unusual noise such as grinding, screeching, or rattling may indicate bearing failure or impeller damage. Water leaking from the seal area means the carbon-graphite seal has worn and requires replacement. If the motor repeatedly trips the breaker, there may be an electrical fault or the GFCI is detecting a ground current — discontinue use immediately and have the pump inspected. Reduced water flow could indicate a clogged impeller, worn seal, or failing motor. Motor overheating or a burning smell indicates the motor windings may be damaged.

Seal Replacement:

The Circ-Master CMHP uses a carbon-graphite self-lubricating seal (BSP-200) compatible with the Aqua-Flo Viton 200 shaft seal kit. Replace the seal at the first sign of leakage. Both halves of the seal (carbon and ceramic) should be replaced together every time the pump is disassembled. Ensure seal surfaces are smooth, clean, and free from damage before reassembly.

Winterization:

To prevent damage during freezing conditions, disconnect all electrical power, drain the pump thoroughly using the wing nut drain plugs at 3, 6, and 9 o’clock positions, and clean out any debris. Protect the pump and motor from the elements by covering or, if possible, store in a dry, well-ventilated room.
